i emailed quaife asking about their diff's for our s2k's. the reason why there is so much interested in their diff's is because there is no clutches to replace like other diff's and they have lifetime warranty. here's their response:

"Wallace,

Thank you for your inquiry. Unfortunately, there are no current plans at
this time to produce a unit for the S2000. One can be developed, but a
minimum of 30 units must be ordered. We would require a sample diff and
drive flange to pattern from and quote pricing. If there is that much
interest on your newsgroup, perhaps a unit could be developed for an
introductory special price?

Regards,

Ralph Hollack

so what diff do you guys recomend?
